A large nuclear power plant would be likely to use in the transformation process because having humans perform these tasks would put them at risk.

A large nuclear power plant would be likely to use in the transformation process because having humans perform these tasks would put them at risk.

The answer is "robots"

Explanation:

Nuclear power is electricity generated by power plants that derive their heat from fission in a nuclear reactor, and, it is an efficient way of making turbines to produce electricity by using steam.

Nuclear power plants consist of some equipment such as, electric generators, steam generators, turbines, pumps. It uses low-enriched uranium fuel to produce electricity by splitting of uranium atoms in a nuclear reactor. Nuclear power plants heat water to produce steam. The process brings about the release of energy by splitting atoms to form smaller atoms. The energy conversions in Nuclear power plants are: Nuclear energy is converted into thermal energy, thermal energy is converted into mechanical energy, and mechanical energy is converted into electric energy.

Nuclear power plants could become  target of  terrorist attack, leading to radiation exposure. There is concern of nuclear power plants leading to risk of cancer, high-level waste.

Robots enable nuclear applications reach areas where the thermal or radiation environment limits the presence of a human. Robots are essentially important in the transformation process, as they relieve humans from risk that might arise from doing the work themselves. Robots also do tasks such as handling heavy radioactive loads.
